Description Allometry in the freshwater mussel Parreysia corrugata was studied from east-flowing riverDaya, Bhubaneswar, India. The results indicated that shell length (SL)-shell height (SH) andshell length-shell width (SW) relationships for P. corrugata were SH = 0.876 + 0.932SL andSW = 0.625 + 0.898SL. Greater correlation was found between SL and SW than between SLand SH. The length-weight, height-weight and width-weight relationships of P. corrugata wereestablished as TW = 0.00038SL2.80, TW = 0.0006SH2.95 and TW = 0.0023SW2.97 respectively.The t-test value of b indicated an isometric growth pattern in the width-weight and theheight-weight relationships. The highest r2 value was obtained for shell length-total weightand shell height-total weight equations. Present study will be helpful in strengthening theknowledge on interrelationship between the morphometric variables of P. corrugata and alsoin comparing with the earlier studies to know the existence of spatial or temporal variabilityin the morphometry of this species. This information can also be used to better understandthe biology of P. corrugata and to improve the management of this species.
